Description

The present invention relates to an information processing device, an information processing system, an information processing method, and a program used in a thin client system.

In companies, information processing devices used by employees are being migrated to thin client-server systems in order to facilitate security measures and management. In a thin client-server system, remote desktop operation is the mainstream. In this case, the thin client terminal transfers the screen information of the application or file running on the server to its own terminal via the network and displays it, and operates on the screen of its own terminal to perform such an operation. The processing corresponding to is being executed on the server.

Therefore, in the remote desktop method described above, the operation is performed only on the server, and therefore, when the network is disconnected, the operation cannot be continued on the thin client terminal side. For example, in an environment where the network is congested or unstable, the communication network is frequently temporarily disconnected, but the work cannot be continued each time, and the network must be restored. As a result, there arises a problem that the work efficiency of the user is lowered and the convenience is lowered.

Japanese Unexamined Patent Publication No. 2008-210071

Here, the thin client-server system disclosed in Patent Document 1 discloses a technique for interrupting work when a communication path failure occurs and making it impossible to continue processing. Specifically, in Patent Document 1, the client side usually operates a text editor executed on the server side to send character information to the server and also stores it in a memory buffer on the client side. Then, when the occurrence of a communication failure is detected, the client side starts a text editor and loads the character information stored in the memory buffer to continue the work.

Further, in Patent Document 1, when the communication failure is recovered, the text content input to the text editor executed on the client side is accumulated in the buffer, and the text content is transmitted to the server so that the text editor on the server side can be used. Restoring.

However, the method of Patent Document 1 described above has a problem that it is difficult to continue the work quickly and accurately when a communication failure occurs or recovers. For example, when a failure occurs, it is necessary to launch an application on the client side, which may cause a waiting time for work continuation, which causes a problem that work efficiency is lowered. In particular, in an unstable communication environment in which communication is frequently disconnected, it becomes difficult to continue the work by the above-mentioned method, and the convenience of the user is lowered.

Further, in the method of Patent Document 1, only the character information input on the client side is reproduced on the server side, and the input procedure is not considered. For this reason, when an operation in which the input procedure is important is performed on the client side, the accurate work content cannot be taken over at the time of restoration on the server side, and it becomes difficult to continue the work.

Therefore, an object of the present invention is an information processing device, an information processing system, which can solve the above-mentioned problems that it is difficult to continue work quickly and accurately in the event of a communication failure in a thin client-server system.

<Embodiment 1>
The first embodiment of the present invention will be described with reference to FIGS. 1 to 7. 1 to 3 are diagrams for explaining the configuration of an information processing system. 4 to 7 are diagrams for explaining the operation of the information processing system.

[Constitution]
As shown in FIG. 1, the information processing system in the present embodiment is composed of a server 10 connected via a network and a plurality of thin client terminals 20. The network may be any communication network such as a wired LAN (Local Area Network), a wireless LAN such as WiFi, and mobile communication.

Then, the server 10 provides execution data such as an application program or a file to the thin client terminal 20 operated by the user 30, and provides a working environment in which the execution data is executed (expanded or opened). It realizes the service. That is, the information processing system in this embodiment constitutes a so-called thin client-server system. Hereinafter, each configuration will be described in detail.

The server 10 (server device) is composed of one or a plurality of information processing devices provided with an arithmetic device and a storage device. Then, as shown in FIG. 2, the server 10 includes a service providing unit 11 and a synchronization unit 12 constructed by the arithmetic unit executing a program. Further, the server 10 includes a service data storage unit 13 formed in the storage device.

The service providing unit 11 (execution data transmitting means) transmits execution data such as an application or a file in response to a request from the logged-in thin client terminal 20. The applications and files are stored in the service data storage unit 13 in advance.

The synchronization unit 12 (execution data manipulation means) transmits the application or file requested from the thin client terminal 20 to the thin client terminal 20, and also executes the application or file on the server 10. Then, as will be described later, when the synchronization unit 12 receives the work information representing the operation contents of the application or file being executed on the thin client terminal 20 from the thin client terminal 20, the synchronization unit 12 receives the work information representing the operation contents of the application or the file executed on the thin client terminal 20, based on the work information. Operate applications and files running on the server 10. At this time, since the work information includes the order information indicating the operation procedure, the application or the file is operated by the operation procedure according to the order information. As a result, the application or file running on the thin client terminal 20 and the application or file running on the server 10 can be synchronized.

The synchronization unit 12 performs an operation based on the work information each time it receives work information sequentially transmitted from the thin client terminal 20, but the connection between the server 10 and the thin client terminal 20 is disconnected and restored. In some cases, a plurality of work information may be collectively transmitted from the thin client terminal 20. In such a case, the synchronization unit 12 sequentially operates the collectively received work information according to the order information included in the received work information.

Further, when the operation (synchronization) for the application or file executed on the server 10 based on the work information received from the thin client terminal 20 is completed, the synchronization unit 12 indicates that the operation of the work information is completed. Notify the client terminal 20.

The thin client terminal 20 (information processing device, client terminal) is composed of an information processing device including an arithmetic unit and a storage device. Then, as shown in FIG. 2, the thin client terminal 20 includes an execution data acquisition unit 21, an execution unit 22, and a work information processing unit 23, which are constructed by the arithmetic unit executing a program. Further, the thin client terminal 20 includes an execution data storage unit 24 and a work information storage unit 25 formed in a storage device (storage means).

The execution data acquisition unit 21 (execution data acquisition means) performs a process of logging in to the server 10 by the thin client terminal 20, and executes execution data such as an application or a file to be executed by the thin client terminal 20 with respect to the logged-in server 10. To request. Then, the execution data acquisition unit 21 receives the application or file transmitted from the server 10 in response to the request, and stores the application or file in the execution data storage unit 24.

Further, as will be described later, the execution data acquisition unit 21 deletes the application or file from the execution data storage unit 24 when the execution of the application or file acquired from the server 10 on the thin client terminal 20 is completed. At this time, the execution data acquisition unit 21 deletes the application or the file when it is confirmed that the work information does not exist in the work information storage unit 25, as will be described later.

The execution unit 22 (execution means) acquires execution data from the server 10 as described above, reads execution data such as applications and files stored in the execution data storage unit 24, and executes the execution on the thin client terminal 20. That is, if the thin client terminal 20 is an application, it is expanded and operated on the terminal, and if it is a file, it is opened. As a result, the user 30 can execute the application or file provided by the server 10 on the thin client terminal 20 that is directly operated. Then, the user 30 inputs the operation information indicating the content of the operation for the application or the file executed on the thin client terminal 20, and the process based on the operation information is executed on the thin client terminal 20.

When the operation information for the application or file executed on the thin client terminal 20 is input, the work information processing unit 23 (work information processing means) associates the operation information with the order information indicating the operation procedure. , It is stored in the work information storage unit 25 as work information. For example, as shown in FIG. 3, the work information processing unit 23 assigns a "sequential number" as sequence information, and "sequential number" indicates a window to be operated on the thin client terminal 20. The work information associated with the "target window" and the "operation information" indicating the specific operation content is stored.

As an example, when the operation "the coordinates xxx and yyy are double-clicked on the window A" is performed, the work information processing unit 23, as shown in the sequential number "01" in FIG.
[Sequential number 01 Window A coordinate xxx, yyy double click]
Work information is accumulated and saved.
Further, as another example, when the operation "character string CCC is input to the window B" is performed, the work information processing unit 23 is shown in the sequential number "02" in FIG. To,
[Sequential number 02 Window B CCC character input]
Work information is accumulated and saved.

Further, the work information processing unit 23 transmits the work information stored in the work information storage unit 25 to the server 10. At this time, in the state where the thin client terminal 20 is connected to the server 10, the work information processing unit 23 sequentially inputs an operation by the user 30 and stores the work information in the work information storage unit 25. The work information is transmitted to the server 10. The work information processing unit 23 keeps the transmitted work information stored in the work information storage unit 25.

The work information processing unit 23 cannot transmit work information to the server 10 when the thin client terminal 20 is not connected to the server 10 due to a network failure or the like. In this case, the work information processing unit 23 stores the work information in the work information storage unit 25 and keeps it stored. Then, the work information processing unit 23 transmits the work information stored in the work information storage unit 25 to the server 10 after the connection between the thin client terminal 20 and the server 10 is resumed. At this time, if a plurality of work information is stored in the work information storage unit 25, the plurality of work information are collectively transmitted to the server 10. Even in such a case, the server 10 can recognize the operation order of the work information by the above-mentioned sequence number.

Then, when the work information processing unit 23 receives the notification of the information that the operation by the server 10 for the work information transmitted to the server 10 is completed, the work information processing unit 23 deletes the corresponding work information from the work information storage unit 25. For example, the server 10 sends a notification such as [Sequential number 01 completed] in which a "sequential number" that specifies work information and information indicating completion are associated with each other. From such a notification, the work information processing unit 23 identifies the work information in the work information storage unit 25 and deletes it from the work information storage unit 25.

Here, the operation input from the user 30 to the application or file executed on the thin client terminal 20 is for data that has not been acquired from the server 10 and is not stored in the execution data storage unit 24. There may be. At this time, if the thin client terminal 20 and the server 10 are disconnected, the thin client terminal 20 cannot execute such an operation. Therefore, the work information processing unit 23 deletes the work information corresponding to such an operation from the work information storage unit 25. That is, the work information processing unit 23 stores the work information in the work information storage unit 25 when the operation is input, but the work information storage unit 25 works at the timing when it is found that the operation cannot be executed. Delete the information. However, the work information processing unit 23 does not have to store the work information due to the above-mentioned unexecutable operation in the work information storage unit 25 from the beginning.

[motion]
Next, the operation of the information processing system having the above-described configuration will be described mainly with reference to the sequence diagrams of FIGS. 4 to 6. Note that FIG. 4 shows the operation in a state where the thin client terminal 20 and the server 10 are connected. FIG. 5 shows an operation in a state where the thin client terminal 20 and the server 10 are disconnected, and FIG. 6 shows an operation in a state where the connection between the thin client terminal 20 and the server 10 is restored.

First, with reference to FIG. 4, the operation in a state where there is no failure on the network and the thin client terminal 20 and the server 10 are connected will be described.

When the user 30 performs a login operation on the thin client terminal 20 (step S1), the thin client terminal 20 makes a login request to the server 10 (step S2). Then, the server 10 executes a login process for the login request from the thin client terminal 20 (step S3).

When the login of the thin client terminal 20 is completed, the user 30 can access the application or file on the server 10 via the thin client terminal 20. That is, the server 10 starts and executes execution data such as an application or a file on the server 10 in response to an application execution request or a file browsing request from the thin client terminal 20 (steps S4 and S5) (step S6). ). In addition to this, the server 10 transfers the running application or file to the thin client terminal 20 (step S7).

By storing the transferred applications and files in the execution data storage unit 24, the thin client terminal 20 can operate independently on the thin client terminal 20. In this state, the user 30 executes an application or a file on the thin client terminal 20 (step S8).

The thin client terminal 20 manages a startup window while executing an application or a file (step S9). Specifically, when the thin client terminal 20 receives an input of an operation for an application or a file from the user 30 (step S10), the thin client terminal 20 manages which window the operation, for example, each keyboard input or mouse operation is for. ..

Then, the thin client terminal 20 operates the input operation content for the application or file being executed, and stores the operation content as work information in the work information storage unit 25 (step S11). At this time, as shown in FIG. 3, the thin client terminal assigns a sequential number indicating the order of operations for each operation, and accumulates work information including the window to be operated and the operation information indicating the operation contents. .. The operation information includes, for example, characters input by the keyboard, clicks, double clicks, and drags on certain coordinates with the mouse.

After that, the thin client terminal 20 transfers the work information stored in the work information storage unit 25 to the server (step S12). The server 10 that has received the work information from the thin client terminal 20 performs an operation based on the received work information on the application or file running on the server 10 to perform an operation on the thin client terminal 20 and the server. 10 Synchronize the operation with the above (step S13). At this time, since the work information is given a sequential number indicating the operation order, the server 10 can perform the operations in the same order as the operations performed on the thin client terminal 20, and the processing contents are matched. Can be taken. In particular, as will be described later, even when the thin client terminal 20 and the server 10 are disconnected, the operation on the thin client terminal 20 during that time can be accurately reproduced on the server 10.

When the execution of the operation based on the work information transferred from the thin client terminal 20 is completed, the server 10 notifies the thin client terminal 20 of the end of the operation (step S14). For example, the server 10 notifies the thin client terminal 20 of the sequential number of the completed work information and the fact of completion. When the thin client terminal 20 receives the completion notification for the work information from the server 10, the thin client terminal 20 deletes the work information of the corresponding sequential number from the work information storage unit 25 (step S15). After that, by repeating the above processing, the thin client terminal 20 and the server 10 are continuously synchronized.

After that, when the work related to the execution of the application or file by the user 30 is completed, the user 30 performs a logoff operation from the server 10 of the thin client terminal 20 (step S16). Then, the thin client terminal 20 confirms that no work information remains in the work information storage unit 25, and then deploys the applications and files on the thin client terminal 20, and further, the execution data storage unit 24. The application or file stored in is deleted from the thin client terminal 20 (step S17). As a result, the execution data such as applications and files on the server 10 becomes the only data. At this time, if the work information is still accumulated in the thin client terminal 20, there is a possibility that the information may be leaked from the thin client terminal 20 for security reasons. Further, if the user 30 updates the file by another terminal operation and then launches the file from the thin client terminal 20 again, the file inconsistency may occur. Therefore, after confirming that the work information has been completely deleted, the application and the file are deleted from the thin client terminal 20.

After that, the thin client terminal 20 notifies the server 10 of the logoff (step S18), and the server 10 performs the logoff process (step S19).

Next, with reference to FIG. 5, the operation in the state where the thin client terminal 20 and the server 10 are disconnected due to a network failure will be described.

When the thin client terminal 20 detects the disconnection of the network (step S21), the thin client terminal 20 displays on the screen and notifies the user 30 that the network is disconnected (steps S22 and S23). Even in such a case, since the thin client terminal 20 is executing the application or file stored in its own terminal, the work can be continued as it is.

When the user 30 inputs characters to the thin client terminal 20 with a keyboard or operates with a mouse in such a network disconnection state (step S24), the execution process of such an operation is performed on the thin client terminal 20 as described above. It is said. Then, as described above, the thin client terminal 20 stores the work information in which the operation information is given a sequential number in the work information storage unit 25 (step S25). At this time, the work information is not transferred to the server 10 due to the network disconnection, and the thin client terminal 20 continues to accumulate the work information each time the operation is performed. Therefore, during this period, the applications and files being executed cannot be synchronized between the thin client terminal 20 and the server 10, and the states are different. However, since each work information is given a sequential number, the order of operations on the thin client terminal 20 is guaranteed, as will be described later.

Here, since the server 10 cannot be accessed in the network disconnected state, it is not possible to newly access applications and files that are not stored on the thin client terminal 20. Therefore, if the user 30 performs an operation to access a new application or file (step S26) and finds that the process cannot be executed by the thin client terminal 20 (step S27), the thin client terminal 20 cannot be executed. Is displayed and the user 30 is notified (steps S28 and S30). At the same time, the thin client terminal 20 deletes the work information representing the content of the operation at this time from the work information storage unit 25 (step S31).

For example, suppose that the user 30 tries to start a new application and performs an operation of "double-clicking the coordinates xxx and yyy on the window A" on the thin client terminal 20. Then, the work information [sequential number ZZ window A coordinate xxx, yyy double-click] corresponding to the operation is stored in the work information storage unit 25. However, when the thin client terminal 20 finds that the operation cannot be executed in the state of network disconnection, the thin client terminal 20 notifies the user that the operation cannot be executed, and the work information of the "sequential number ZZ" is transmitted from the work information storage unit 25. Delete from the accumulated information.

Next, with reference to FIG. 6, the operation of the state in which the thin client terminal 20 and the server 10 are connected after the network is restored after the failure of the network of FIG. 5 occurs will be described.

When the thin client terminal 20 detects the restoration of the network (step S41), the thin client terminal 20 sequentially transfers the work information stored in the work information storage unit 25 to the server 10 (step S42). The thin client terminal 20 may collectively transfer a plurality of work information to the server 10.

When the server 10 receives the work information from the thin client terminal 20 after the network recovery, the server 10 sequentially executes the operation of the work information of the subsequent sequential numbers with respect to the sequential number of the work information executed before the network recovery (step S43). ).

Then, when the execution of the operation based on the work information transferred from the thin client terminal 20 is completed, the server 10 notifies the thin client terminal 20 of the end of the operation (step S44). When the thin client terminal 20 receives the completion notification for the work information from the server 10, the thin client terminal 20 deletes the work information of the corresponding sequential number from the work information storage unit 25 (step S45). The thin client terminal 20 sequentially transfers the work information to the server 10 until the work information stored in the work information storage unit 25 is exhausted, and deletes the work information in response to the receipt of the completion notification.

The thin client terminal 20 completes the synchronization on the thin client terminal 20 and the server 10 when all the accumulated work information is exhausted (step S46). Then, the thin client terminal 20 releases the network disconnection information displayed to the user 30 (steps S47 and S48). After that, it recovers to the normal operating state.

As described above, according to the information processing system of the present invention, even if the network is disconnected, since the application or file is executed on the thin client terminal 20 before the disconnection, the work can be continued as it is. can. Further, during the network disconnection, the thin client terminal 20 specifies the operation order and accumulates the work information, and after the network is restored, the work information is transferred to the server 10 for synchronization. Therefore, the thin client terminal 20 and the server 10 perform the operation information. It can be surely matched. Therefore, the network connecting the thin client terminal 20 and the server 10 is in an environment in which communication is interrupted in an unstable network environment such as a wireless network, or it becomes temporarily difficult to connect due to concentration of access. However, it is possible to continue work quickly and accurately.

[Modification 1]
Next, a modified example of the above-mentioned information processing system will be described with reference to FIG. 7. The information processing system in this example further includes the following configurations in addition to the configurations described above.

First, the service providing unit 11 (execution data transmission means) of the server 10 executes execution data such as an application or a file on the server 10 in response to a request from the logged-in thin client terminal 20 as described above, and such execution. The data is transmitted to the thin client terminal 20 (steps S1 to S7). At the same time, the service providing unit 11 transmits the operation screen of the execution data executed on the server 10 to the thin client terminal 20 (step S51). That is, while transmitting the application or file to the thin client terminal 20, the server 10 provides a work environment by remote desktop until the acquisition of the application or file by the thin client terminal 20 is completed and the execution is started.

Then, the execution data acquisition unit 21 (execution data acquisition means) of the thin client terminal 20 is transmitted from the server 10 while storing the application or file transmitted from the server 10 in the execution data storage unit 24 (step S8'). Display the operation screen (step S52). That is, the thin client terminal 20 displays the operation screen of the application or file being executed on the server 10 until the reception of all the data of the application or file is completed.

The user 30 performs an operation on the operation screen displayed on the thin client terminal 20 (step S53), and the execution unit 22 (execution means) of the thin client terminal 20 transmits information on the operation content on the operation screen to the server. Transfer to 10 (step S54). When the synchronization unit 12 (execution data operation means) of the server 10 receives the operation information for the operation screen from the thin client terminal 20, the synchronization unit 12 (execution data operation means) performs the processing of the operation content on the application or file being executed on the server 10. (Step S55). Then, the operation on the operation screen transmitted from the server 10 is continued until the thin client terminal 20 acquires the application or file from the server 10 and executes it.

After that, when the acquisition of the application or file transmitted from the server 10 by the thin client terminal 20 is completed (step S56), the thin client terminal 20 switches to the execution of the application or file stored in itself (step S58). At the same time, the server 10 ends the provision of the operation screen (step S57). After that, in the same manner as described above, the operation for the application or file executed on the thin client terminal 20 is performed, the work information including the operation content is accumulated, and is provided to the server 10 (step S9 or later). ..

As described above, the thin client terminal 20 in this example can operate the application or file running on the server 10 during that time without waiting for the completion of downloading the application or file from the server 10. Therefore, the user 30 can start the work quickly.

Even if the network is disconnected during deployment even after the download of the application or file is completed, the data of the application or file is already stored in the thin client terminal 20, so the execution of the application or file is continued. can. In addition, if a network disconnection occurs while downloading an application or file, it is said that the application or data cannot be executed as described above.

[Modification 2]
Next, a modification of the above-mentioned information processing system will be described. In the information processing system in this example, the thin client terminal 20 and the server 10 store the same application in advance, and both the thin client terminal 20 and the server 10 can execute the same application. For example, an application that stores in both sides is an application that has a large executable file.

Then, the thin client terminal 20 acquires and stores a file stored only in the server 10 from the server 10 as execution data, and opens the stored file on the thin client terminal 20. The thin client terminal 20 performs an operation on the opened file, accumulates work information including the operation information, and transfers the work information to the server 10.

By doing so, in the information processing system, it is not necessary to transfer the application from the server 10 to the thin client terminal 20, and only the file needs to be transferred as the execution data, so that the transfer capacity can be reduced.

<Embodiment 2>
